LOT has now confirmed 10 tornadoes from March 10. In the EF-3 tornado that tracked from IL into IN, it looks like they upgraded a couple additional swaths of damage in that tornado to EF-3. That supercell went on to produce 2 tornadoes in the IWX cwa, so that supercell produced a total of at least 12 tornadoes.
Was looking at IWX's page of this event and saw a picture when the tornado was near Knox, IN. Just visually, the pic reminded me a bit of the tornado that hit Branch county, Michigan on April 11, 1965. Here are the two pics for comparison:
